Before it goes in

  • Ember Tetra needs at least 30 L (8 gal). The smallest size in this library that clears that is the Dennerle Nano Cube 30L.
  • Keep 8 or more. Below that it hides, colours down and is far more likely to be picked on.
  • Adult shrimp are safe; shrimplets will be eaten, so a shrimp colony will not grow in the same tank.
  • It is the wrong size to share a tank with Goldfish, Angelfish and Axolotl: it ends up as food.
  • It holds at 73–82°F (23–28°C). That shares a window with Betta and Cherry Shrimp.
  • A group of 8 takes up roughly 42% of what a Dennerle Nano Cube 30L will comfortably hold, so plan the rest of the stock around it.

What tank size does it need?

At least 30 L (8 gal). The smallest size here that clears it is the Dennerle Nano Cube 30L.

How many should I keep?

8 or more. Fewer than that and it spends its time hiding instead of out in the open.

Will it eat shrimp?

Adults are safe, shrimplets are not. You can keep shrimp with it; you just will not get a growing colony.

What water does it want?

73–82°F (23–28°C), pH 5.5–7.

How long does it live?

2–3 years in a tank that suits it. That is how long you are signing up for.
